When you get the logs from ESPHome dashboard it will show the dialogue for the i2c component scanning your channel for a device. It will show the address if it finds something. That address is what you then use in your sensor set up. Can you post your full log from the dashboard?
Edit: post text not photo. And make use of the formatting for yaml.
See page 5 of the Atlas pool kit doc for the addresses
…and the little led will be blue when powered on and flick green for a split second each time a reading is taken which is a good indicator things are working….aside from seeing values in any output console you have.
And there is sample Atlas code on their website which (IIRC) has all the i2c addresses.
Here’s the full log from the Dashboard:
It looks like it didn’t find I2C devices, so something must still be wrong.

Exactly how is it all wired up?
It’s the box directly from Atlas with pH, ORP, and Temperature probes. Everything was already preinstalled in the kit, so I just connected the probes to my pool equipment, flashed it with homeassitant using ESPHome dashboard. Took a stab editing the yaml and failed. Did you use the kit directly from Atlas? If so, can I see what your YAML looks like?
This is my latest attempt, but the logs indicate that nothing is working:

According to this Overview | Adafruit HUZZAH32 - ESP32 Feather | Adafruit Learning System the huzzah32 sda/scl pins are 22 & 23. Not 21 & 22 as you have it.
Hi, can you provide some feedback? Did it work with localtuya? Can you maybe post the config?
HI, i must wait for the Device to deliver 
IT WORKED! Thank you! Thank you! Thank you!!!
This forum is the best!
So far it is working, and all three sensors (pH, ORP, and temp) show up in home assistant so I added them to the dashboard as a gauge. I haven’t figured out yet how to calibrate the sensors, but it homeassistant showed my pH as being high and my chlorine (ORP) being low, and a test strip confirmed it so at least it’s not too far off. ORP is reported in mV, and converting to PPM seems difficult. My immediate goals will be to figure out how to calibrate and use some of the statistics functions to give me trending numbers that I can use in my next automations (i.e. turn on my chlorine generator and pH reducer).
@HG901 you should have gotten calibration solutions with your kit. There are ways to calibrate (again, with the solutions) via esphome but I reflashed the original firmware from atlas, did the calibrate and then reflashed again w my esphome config. Ultimately I just bought a second huzzah esp and keep one with the original firmware and one with esphome.
yes, I have the calibration solutions. I did update my yaml to include the lamda buttons I found here for easy calibration. I also used their code to change my temperature readings to Fahrenheit which is nice.
So you’re good to go then? Sounded like you were having problems still.
I think I am good!
Did you calibrate ORP probe as well?
Yes the calibration “kit” has 4 pouches, 3 for the ph calibration and one of the orp.
